calculate

public double calculate(double[] obs,
                        double[] sim,
                        double missingValue)

Description copied from interface: ObjectiveFunction

Calculates the objective function value based on the given simulated and observed values. If measuredValue[i] <= missingValue (where 0<=i

Specified by:

calculate in interface ObjectiveFunction

Parameters:

obs - the observed values

sim - the simulated values

missingValue - the missing value that indicates a observed or/and simulated value is missing

Returns:

the objective function value.

positiveDirection

public boolean positiveDirection()

Description copied from interface: ObjectiveFunction

This method tells you if it is good for the objective function value to be large.

Specified by:

positiveDirection in interface ObjectiveFunction

Returns:

true if a greater objective function value is considered better. false is returned otherwise.
